#51486: qhull requires switches to cmake to build on 10.6.8

     Type:  defect          |     Status:  new
 Priority:  Normal          |  Milestone:
Component:  ports           |    Version:  2.3.4
 Keywords:  build compiler  |       Port:  qhull
----------------------------+--------------------------------
 qhull fails to build on os x 10.6.8 as /Developer/usr/bin/g++-4.2 does not
 understand one of the switches passed to it -Wno-sign-conversion.  Not
 much surprise as it is a 2007 compiler.  To fix this please pass
 -DCMAKE_C_COMPILER=/opt/local/bin/gcc-mp-4.8
 -DCMAKE_CXX_COMPILER=/opt/local/bin/g++-mp-4.8 to cmake and make qhull
 dependent on gcc48.  Perhaps there is an older compiler eg gcc47 which
 will work too, I just tried it with 4.8 to get it working.
